They took a crystal, this is a single crystal of nickel that has regular planes of atoms, and those planes are spaced on the order of an angstrom or less apart, and they irradiated this with x-rays.

他们取了个晶体，一个具有规则原子平面的，镍晶体，这些面间距差不多也是一埃或者更少，它们放射出X射线。

Any given volume of water contains two types of molecular structures-one a blobby, loosely packed agglomeration and the other a tight, regular arrangement resembling a crystal lattice.

任何给定容量的水包含两种类型的分子结构—一种是点点松散的凝聚体，而另外一种是紧凑规则的类似晶体的组合。

But when scientists squeezed tiny samples of a metallic glass under high pressure, they got a surprise: the atoms lined up in a regular pattern to form a single crystal.

但是当科学家在很高的压力下压制微小的金属玻璃样品时，他们得到了一个惊喜：原子以一种固定的模式排列起来而形成了单晶。

In the second mode of working, the crystal fibre uses the regular array of holes to influence light in much the same way as the arrangement of atoms in a crystal can determine whether electrons are able to travel easily through it and hence whether the crystal is electrically conducting or not.

Phonics teaching is an important component of the teaching of reading, but not all words in English are phonically regular (the linguist David Crystal estimates 80% are, but the other 20% contains many of the most common words in English).

Quartz watches use very high-frequency oscillations of a crystal, which can be tuned with extreme precision to produce regular signals.
